After hearing Liang Yuan say this, Su Liangyu laughed and said, "Then I'm not polite."

Su Liangyu stretched out three fingers and shook it and said, "It is not counted that the chip laboratory invested now, and to bring the project closer to the practical level of the project. Xiaoyuan needs to invest at least 300 people. If the bottom of the car and the traction nose are counted, it will take at least 500 people to make the project officially run."

Liang Yuan smiled bitterly and said, "At present, all the technicians in the Ministry have not yet reached 1,000 people. Lao Su, you have directly turned the scale of the project team into half of the Railway Research Institute. Where can I find people?"

"Haha, that's your problem, but with fewer people, the development progress will be slower." Su Liangyu said with a smile.

In order to take out samples of the air purifier before the Canton Fair in May, Su Liangyu threw all the matter of establishing a project team from Helu Bureau Signal Factory to Liang Yuan. However, Su Liangyu was quite conscientious and transferred Wang Xin, the backbone of the chip laboratory, to temporarily be responsible for specific affairs.

In the 1980s, the railway computer interlocking system, not to mention the signal factory of the Road Bureau, was searched all over the country, and there were only some relevant talents in the Communications Signal Research Institute under the Railway Research Institute. Liang Yuan planned to tie the gas turbine locomotive into the entire railway system. It was far from enough to rely solely on computer interlocking. At least the locomotive signal (Note 1) and the train operation monitoring device must be developed together, and then integrated into a huge signal network composed of ground signal mechanisms. After doing these, this huge network is just beginning.

Liang Yuan shook his head with the thin development plan drafted by the Road Bureau Signal Factory.

The Road Bureau Signal Factory simply listed the various benefits of using cost and reliability after the ground signal and electric switch machine were replaced with chip control. Then it greatly introduced the computer interlocking system put into use by the Railway Research Institute on the underground transportation line of Meishan Iron Mine in Nanjing in 1984. It plans to integrate the new signal and switch machine with the Meishan Iron Mine system in the future to build a new railway signal management system.

Liang Yuan, who has a clear understanding of the future, knows that the development plan of the Road Bureau Signal Factory is about the same as a joke.

The progress of China's railway system began with the largest railway driving accident in the history of New China, the "Yangzhuang Tragedy". In 1978, near Yangzhuang Station in Lankao County, Longhai East Line, train 368 from Xi'an to Xuzhou collided with train 87 from Nanjing to Xining. 106 people died in the accident, 171 were slightly injured and 47 were seriously injured.

The cause of the accident was that the two head and deputy drivers of the 368 train, Ma Xiangchen and Yan Jingfa, were asleep at the same time when approaching Lankao Station. The 368 times that should have been waiting for refuge at Lankao Station crossed the blood-red exit signal and rushed out of Lankao. In the end, the 368 times that were "unmanned" collided with 87 at Yangzhuang Station.

The world was shocked after the accident. As it was the eve of reform and opening up, the central government attached great importance to the accident. While handling the two drivers who had been sleeping illegally, they also gave relevant management personnel the administrative demerits, including the Deputy Minister of Railways...

After the "Yangzhuang Tragedy", advanced railway management concepts such as locomotive signal systems and automatic parking systems were put on the working agenda by the Ministry of Railways. However, due to the weak electronic foundation in China and the backward management thinking of the railway system (Note 2), this work made almost no progress in the entire 1980s.

A few days ago, in order to appease the automatic brake system developed by the Ministry, Liang Yuan added a motor to control the brake duct by the Railway Research Institute, which turned into his own achievements. He hyped it up for two periods in the People's Railway News, and then began to promote it on passenger aircraft heads under a series of internationally advanced names.

In fact, if Liang Yuan had not intervened, it was not until the mid-1990s that the Ministry of Railways introduced the tvm300 and tvm430 general locomotive signal systems in France that the problem of locomotive signal was solved. As for the automatic parking system, although the Ministry of Railways said that after entering the new century, the independently developed ctcs (Note 3) system had solved the problem of automatic parking in dangerous situations, but the world-renowned high-speed rail accident in Wenzhou was slapped in a loud slap in the face of the Ministry of Railways.

Since Su Liangyu has the ability to solve the needs of railway signal systems in hardware, Liang Yuan plans to officially enter the railway signal industry, naturally he can no longer use the loophole development plan created by the Road Bureau Signal Factory.

In the next few days, Liang Yuan stayed honestly in the 909 community, trying hard to recall the ctcs system promoted by the Ministry of Railways in the previous life after the new century.

The ctcs system consists of a large number of transponders, track circuits, wireless communication networks (gsmr), train control centers (tcc) and wireless occlusion centers (rbc) and other parts. The core of the entire system is the transponder and receiver. The transponder can transmit the information of the ground signal to the receiving equipment of the machine head, while the ground signal checks the occupation of the interval track through the track circuit reception device. After judging through the chip, the signal is directed to make relevant signal reactions.

Liang Yuan stayed in the 909 community for three days before he formed text on the principles, equipment structure, short-term planning, long-term planning and other issues of the previous life's ctcs system, and restored the entire ctcs system in the framework.

On February 23, Liang Yuan took the fruits of his labor for the past few days and returned to the Science and Technology Park with a thick stack of handwritten materials. He went to Su Liangyu's office on a routine basis. Liang Yuan, who was pushing the door, found a middle-aged man with glasses sitting on the sofa where Liang Yuan usually sat.

"Mr. Su, my uncle asked me to give you this." Liang Yuan shook the documents in his hand and said.

Su Liangyu signaled the man wearing glasses to wait and take the documents handed over by Liang Yuan.

"ltcs, train operation control system." Su Liangyu looked at the big words on the cover of the document and read them casually.

Liang Yuan shamelessly removed the Chinese train control system in his previous life, representing the mother and child of China, and replaced it with the first pinyin of his surname "l."

Su Liangyu picked up the document and started to look through it intently.

In Liang Yuan's plan, the ltcs system was divided into five stages. At the beginning, the foundation was to build the foundation, and a large number of digital signal machines, switch machines, general locomotive signal machines, and train operation monitoring devices formed the basic digital system of the entire railway. During this period, the train's operating speed did not exceed 100 kilometers.

After building the basic system, the main locomotive signal machine is developed, and the train marshalling is turned into a locomotive signal operation based on observation of ground signals, and a safe operation monitoring and recording device is established. By comparing and judging with historical operation records and signals, the anti-speeding function of automatic deceleration can be realized. After completing the anti-speeding system, the operating speed of the train can be increased to a speed of 120 kilometers per hour.

Finally, it is a train operation control system designed based on track transmission information and adopts a vehicle-to-ground integrated system. It can realize the integration of driving command computer interlocking train control, the integration of interval stations, the integration of communication and signal and the integration of mechatronics. Section scheduling can intuitively grasp the real-time situation of all signal machines, switches, and running trains in this section at any time, and can detect signs of crisis driving safety accidents as soon as possible.

Twenty minutes later, Su Liangyu let out a long sigh, raised the information in his hand, and said to the man on the sofa: "Meng Gong, there is a document for building a railway signal system here. Meng Gong can take a look. After reading it, we will discuss which unit will lead the development of a brand new signal system."

Note 1: Because ordinary signal machines are installed on the ground, they are restricted by railway curves, tunnels and other terrain, which brings certain difficulties to the driver's attention. Especially in harsh climates such as rain, snow, wind, sand, and fog, the ground signal is even more difficult to see clearly. The locomotive signal is a sensor installed on the traction machine head. After receiving the signal from the ground signal, the locomotive signal continuously displays the same signal as the ground signal in front.

Note 2: In the 1980s, even portable signal lights were high-tech products in the railway department. Usually, they used red and green triangular flags to direct trains.

Note 3: ctcs is the China Railway Train Operation Control System.
